Transfer tables for LMT8x Temperature Sensors.
LMT8x (LMT84, LMT85, LMT86, LMT87) are a series of analog temperature sensors made by Texus Instrument. These sensors can provide -50°C ~ 150°C with ±0.4°C accuracy. Although the output voltage is nearly linear to the temperature, it does have a slight umbrella parabolic shape. Therefore transfer tables are required to convert the voltage to the temperature.
Datasheets:
This package provides tranfer functions for LMT84, LMT85, LMT86, and LMT87 based on their transfer tables. These funcitons basically do a binary search through the transfer tables and return the match. If no match found, linear interpolation will be used to generate an approximate value.
Installation
pip install lmt8x
You can also install the in-development version with:
pip install https://github.com/charlee/python-lmt8x/archive/master.zip
Usage
lmt8x package provides functions lmt84_v2t, lmt85_v2t, lmt86_v2t, and lmt87_v2t for converting voltage to temperature.
input voltage must be in mV.
output temperature is in celsius.
from lmt8x import lmt87_v2t # or `lmt86_v2t`, `lmt85_v2t`, `lmt84_v2t`
# read voltage from sensors.
# v = read_sensor()
# convert v to temperature.
# the pamaeter must be in mV. Return value is in celsius.
temp = lmt87_v2t(v * 1000)
print('Temperature is %s C.' % temp)
